"If Poland is indeed right that Russia is about to increase its presence in the east of Ukraine, buyers of all things risk will disappear fast as this is an indefinable outcome for markets," IG strategist Evan Lucas told Dow Jones Newswires.
CMC Markets added: "The potential of an invasion in Ukraine sent investors scurrying for the exits as they find the slightest excuse to scale off profits."
